Rhizome creeping, tomentose. Stipes scattered, + 1 — 2'/^ cm. long, 

 naked, wiry. Fronds ovate-oblong, + 5—7''.^ cm. long, 2';2— 4 cm. broad 

 near the base, 3-pinnatifld, the main rachis not winged, sulcate above, 

 rounded beneath. Pinnae horizontal or spreading, shortly petiolulate, to 

 2 cm. long, to 1 cm. broad at the truncate base, cut down to a winged 

 rachis into deeply pinnatifid pinnulae. Ultimate segments 1 — 3 on a 

 side, to 2 mm. long and % mm. broad, rounded or bluntish at the apex, 

 the lowest sometimes forked ; edges often more or less distinctly crispato- 

 undulate, provided with an intramarginal spurious vein. Texture thin, 

 membranaceous; surfaces naked; rachises, costae, costulae and veins 

 deciduously gianduloso-JSbrillose beneath; a central vein carried in each 

 ultimate segment. Sori numerous in the adult plants, partly terminal 

 on the pinnae and higher pinnulae, partly solitary at the base of the 

 lower pinnulae on the anterior side, partly forming a compound panicle 

 in the upper part of the frond ; indusium infundibuliform, rather obconical, 

 winged, the mouth dilated, spreading, 2-lobed. — Lower pinnae 

 resembling single fronds of T. humile Forst.

Pinnae not invariably distant, occasionally the main rachis more 

 broadly margined, the ultimate segments a little broader, and the 

 abnormal fronds to 5-pinnate, less finely dissected.

(46a) T. luicroSirioi); CopeL, in Philipp. Journ., X*^, 146. 



Rhizome wide-creeping, filiform, densely clothed with short, black 

 hairs. Stipes slender, 5 — 15 mm. long, terete, naked except at the base- 

 Fronds ovate, 4 — 6 cm. (?) long, the rachis not winged. Lower pinnae 

 short-stalked, the stalk not winged; central pinnae the largest, oblong, 

 obtuse, cut down to a narrowly winged rachis, the segments divided into 

 2 — 5 linear or linar-oblong lacinulae about '/a i^^™- broad, the margin not 

 or slightly crisped, provided with an interrupted, submarginal spurious 

 vein. Sori terminal, scattered or paniculate; indusium narrowly obconical, 

 2-marginate, the mouth broad, conspicuous, spreading or revolute; 

 receptacle included.
